Electric Literature of 7287-81-2, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 7287-81-2, name is 1-(m-Tolyl)ethanol. This compound has unique chemical properties. The synthetic route is as follows.
General procedure: 2,2,6,6-Tetramethylpiperidine 1-oxyl (TEMPO, 9.4 mg,0.06 mmol, 3 mol %), 2,2?-bipyridyl (9,4 mg, 0.06 mmol,3 mol %), [Cu(CN)4]OTf (22.6 mg, 0.06 mmol, 3 mol %) and1-methylimidazole (NMI, 11.5 mg, 11.2 muL, 0.14 mmol,7 mol %) were placed in a zirconia-milling beaker (45 mL)equipped with four balls (two balls × 5 mm , two balls ×12 mm ) of the same material. The jar was sealed and ballmilled for 1 min. Then, benzyl alcohol (216.3 mg, 207 muL,2.0 mmol), NaCl (1.0 g) together with other two zirconia balls(12 mm ) were added and the reaction mixture was subjectedto grinding for further 10 minutes overall (two cycles of5 minutes each). The first milling cycle was followed by a breakof 2 min leaving in the meantime the uncovered jar in open air.The progress of the reaction was monitored by TLC analysis(heptane/AcOEt 9:1 v/v) and GC-MS analysis on an aliquot ofthe crude. Upon completion of the ball milling process, the jarwas opened, the milling balls were removed and the resultingcrude product (adsorbed on NaCl) was then easily transferredinto a separating funnel filled with an aqueous 10% citric acidsolution (20 mL). The aqueous phase was extracted withcyclopentyl methyl ether (or alternatively with AcOEt)(3 × 15 mL). The combined organic fractions were washed withH2O (25 mL) and brine (25 mL), then dried over Na2SO4, andconcentrated in vacuo to give benzaldehyde in high yield (195 mg, 92%) and good purity (>93% by GC analysis). Alternatively, after completion of the reaction, the resulting crudeproduct (adsorbed on NaCl) can be also easily purified by ashort column chromatography on silica gel using heptane/ethylacetate (9:1 v/v) as the eluents to afford pure aldehyde 2b inhigh yield (202 mg, 95%) as a colourless liquid.
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 7287-81-2, 1-(m-Tolyl)ethanol.
